To all whom it may concern.-

Beit known that We, WILLIAM H. COOK and BYZltON D. COOK, citizens of theUnited States, residing at Homer, county of Calhoun, State of Michigan,have invented a certain new and useful Improvementin a Combined FlourBin and Sieve; and we declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification.

Our invention relates to a certain new and useful improvement in acombined flour bin and sieve, designed for the convenient and readysifting of the flour.

The object of our invention is to provide such an article ofmanufacture, of simple and economical construction, and of superiorefficiency, which may be readily handled and operated.

To these ends our invention consists of the construction, combinationand arrangement of devices and appliances hereinafter specified andclaimed, and illustrated in the accompanying drawings, in which I Figure1 is a view in perspective, showing certain features of our invention.Fig. 2 is a view in vertical section. Fig. 3 is a detail View inperspective of the sieve, and Fig. 4 is a similar view of the reel.

We carry out our invention as follows: E represents the upper portion ofthe case of the combined sieve and flour bin, forming an inclosedchamber A, for holding the flour to be sifted.

A represents the lower portion of the inclosing case inclosing a chamberA in which is located a sieve, and into which the flouris received whensifted. The two portions of the case B and A are hinged together on theback side of the case, as shown at a, so that the upper portion B of thecase may be tilted back off from its location upon the lower portion ofthe case. suitable locking device a may be located upon the frontportion of the case B to engage a staple 0, or other similar retainingdevice upon the portion A of thecase, to hold the two portions of thecase firmly to A latch or other gether. The upper portion of the case isprovided also, with a lid A,which may be hinged, as shown at a upon thecase B, a locking device a being provided to hold the lid securely uponthe case B. The case B may also be provided with a suspending eye B,whereby the device may be hung up. The lower portion of the case A isalso preferably provided with a door A, hinged to the base of the case,as shown at a whereby access may be readily had into the chamber A toremove the flour therefrom. It will be understood that the cover A is tobe opened to depositthe fiourto be sifted into the chamber A. The baseof the chamber A is provided with downwardly converging walls 0, ca todirect the flour to the reel and sieve, the walls a a forming a hopperat the base of the chamber A.

C denotes our improved reel, located at the base of the chamber A, saidreel made rotatable and having a series of'wings c. It will be perceivedthat the walls a a forming the hopper, close off the lower portion ofthe chamber A, so as to prevent the flour from falling away from thereel, and from any escape from the chamber A except as directed by thereel, and without being sifted.

D represents the sieve, constructed of concave form.

D represents a screen frame, provided with supports at its ends, markedd and d. These end supports are preferably constructed with journalbearings d and (1 in which the reel is journaled. This frame, it will beunderstood, with the sieve thereto attached, is located in the upperportion of the chamber A and at the base of the chamber A. Said framewith the screen thereto attached, is preferably removable, so that itmay be readily cleaned, when required. By throwing back the upperportion B of the case, the reel may be first lifted out of position, andthe screen with its frame. The reel and screen are thus readilydetachable, and as readily placed in their proper location, whencleaned. The screen may simply be nailed or tacked upon the undersurfaces of the screen frame. At the extremities of the sieve, we locatesemi-circular or arc-shaped end pieces D and D to which the screen isalso fastened. The wings of the reel project into the concavity of thesieve. We prefer to make the upper portion of the sieve flaring, or inother words, to gradually increase the radii of the circle on which thescreen is made, toward the upper edges thereof, thus making the openingbetween the reel or agitator and the screen larger at the top than atthe bottom of the screen. It will be obvious that as so constructed, thewings of the agitator or reel will practically wedge the flour againstthe screen, the wings of the reel gathering the flour into the screen atthe upper portion thereof, and carrying it downward around the circle ofthe screen which decreases in size, in consequence of which the flour iswedged or forced. through the perforations in the screen, without theneed of the violent rubbing and scraping common in other forms ofsieves.

E represents the crank, engaged with the reel, and whereby the reel isrotated. This crank we prefer to construct with an expanded portion e,to be driven into the wood of the reel, to prevent the reel turning onthe handle. The crank may thus form one of the journals of the reel.

The chamber A may be made of sufficient capacity, to hold any desiredquantity of flour, as for example, an ordinary sack of flour. Thechamber may thus readily be made of a size to hold twenty-five, fifty orone hundred pounds of flour, or other quantity as may be desired. Thusthe device may dispense with the frequent handling of the flour, as asack or other desired quantity may be emptied into the bin when firstdelivered, and be stored therein until used up.

What we claim as our invention is- 1. A combined flour bin and sievehaving in combination a case constructed with a lower portion A and withan upper portion B forming interior chambers A and A and hinged togetherupon one side to permit the upper portion being tilted back from itsnormal location over the lower portion, a screen frame D located at theupper edge of the lower portion A of the case and removable therefrom, ascreen engaged with said frame, and a reel journaled upon said framebetween the adjacent edges of the portions A and B of the case, wherebythe reel and screen frame with its screen may be independently removedfrom the case when the upper portion Bis turned back from over the lowerportion, the chamber A extending below the screen and arranged to holdthe sifted flour, substantially as described.

2. Acombined flour bin and sieve having in combination a caseconstructed with a lower portion A and an upper portion B forminginterior chambers A and A and hinged together upon one side to permitthe upper portion B being tilted back from its normal l0- cation overthe lower portion A a screen frame D constructed with side bars D, endsupports (1, d provided with journal bearings upon their upper edges,and with end pieces D D depending therefrom, a screen engaged with saidside bars and end pieces, and a reel journaled in said bearings of saidend supports between the adjacent edges of the portions A and B of thecase, said screen frame D located at the upper edge of the lower portionA of the case and removable therefrom, the reel and screen frame beingarranged to be independently lifted out of their respective locationswhen the upper portion B of the case is turned back from over the lowerportion A thereof, the chamher A formed with a permanent closed base andarranged to hold the sifted flour, substantially as described.

In testimony whereof we sign this specification in the presence of twowitnesses.
